CONVEYER.

SPECIFICATION forming part of Letters Patent No. 552,407, dated December 31, 1895.

Application filed May 7, 1895. Serial No. 548,398. (No model.)

T0 60% whom it may concern.-

Be it known that I, SCOTT WEBBER, of Pigeon Cove, in the county of Essex and State of Massachusetts, have invented a new and Improved Conveyor, of which the following is a full, clear, and exact description. A

The object of the invention is to provide a new and improved conveyer, more especially designed for conveying broken stone and other loose materials from one place to another and depositing the same on the decks of vessels, or in cars, scows' and other means of transportation.

The invention consists of certain parts and details and combinations of the same, as will be fully described hereinafter and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference inclicate corresponding parts in all the figures.

Figure 1 is a side elevation of the improvement. Fig. 2 is an enlarged transverse section of the same on the line 2 2 of Fig. 1. Fig. 3 is an enlarged plan view of the platform and adjacent parts and with parts removed, and Fig. 4 is a longitudinal section of the same on the line 4: A of Fig. 3.

The improved conveyer is provided with a slatted platform Amade endless and mounted to travel on two sets of rolls B and B, of which the set of rolls B is journaled in a stationary frame O, set on a suitable foundation D, such as appear on a river or other abutment. A chute E leads to the inner end of the platform A at or near the rearmost roll of the set of rolls B, as is plainly indicated in Fig. 4, so that material passing down the chute E is directly delivered on the top of the run of the endless platform A. The other set of rolls B is journaled in a frame O, mounted to swing from the frame O, to permit of raising or lowering the frame O, to reach with the outer end the deck of a vessel, scow, car or other means of transportation into which the material is to be loaded.

A joint between the frame 0 and O is preferably made by a rope F on each side of the frames, the said rope F being attached at its ends to brackets F, secured to the frame O, with the middle portion of the said rope pass ing around a pulley on the shaft G of one of the rolls B. The sides of the frames C and O extend a suitable distance above the platform A, as indicated at O O in Figs. 1 and 4, so that the material traveling on the platform A cannot slip off sidewise. A plate O is arranged at the joint between the two frames 0 and C, so that when the latter swings into an inclined downward position, the plate covers the space between the frames.

In order to impart a traveling motion to the platform A, I give a rotary motion to the rolls B from a shaft H, journaled at one side on the frame O, and carrying a beveled gearwheel H adapted to be driven by suitable machinery. (Not shown.) On the shaft H are secured the worms H in mesh with wormwheels H held on the shafts G of several of the rolls B, as indicated in Figs. 1 and 3. Now when the shaft H is rotated, the Worms H impart a rotary motion to the worm-wheels H whereby some of the rolls are rotated and these rolls are provided with projections B engaging recesses in the under side of the slats of the platform A. (See Fig. 2.)

The lowermost run of the platform A travels over auxiliary rollers B j ournaled in the bottom of the frame 0, and a bottom 0 attached to the under side of the frame O, holds the lower run of the platform A close to the rolls B.

The outer end of the frame 0 is connected by stays I with a tackle J of any approved construction, and supported from a side derrick K set in a suitable step on the frame 0 or on the foundation D. Now by manipulating the tackle J, the frame O can be lowered into an inclined position, as indicatedin dotted lines in Fig. 1, or can be raised into an approXimately-horizontal position, as shown in full lines in Fig. 1. the free end of the frame O, and consequently the outer end of the platform, can always be brought into proper position relative to the position of the deck of the vessel or other place where the material is to be loaded.

A gate L is held on the front end of the frame O and is mounted on arms L, pivoted at L to the sides of the frame 0. A tackle N connects the gate L with the tackle J, so that the operator in manipulating the tackle N can swing the gate L upward to permit a ready discharge of the material traveling down the By this arrangement, 1

platform A. The gate L is in a lowermost or closed position on the free end of the frame 0 during the time the frame 0 is lowered and previous to commencing to load.

It will be seen that the device shown and described is very simple in construction, readily manipulated, and arranged to load into vessels irrespective of the rise and fall of the tide.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. A conveyor comprising an endless traveling slatted platform, two sets of rolls on which the platform is mounted, a stationary frame carrying one set of rolls, a swinging frame carrying the other set of rolls, means for rotating some of the rolls in the stationary frame, projections on the said rolls adapted to engage recesses in the under side of the slats of the endless platform and means for raising and lowering the swinging frame, substantially as shown and described.

2. A eonveyer comprising an endless traveling platform, two sets of rolls on which the platform is mounted, a stationary frame carrying one set of rolls, a swinging frame hinged 011 the stationery frame and carrying the other set of rolls, an auxiliary set of rolls in the said stationary frame and over which passes the lower run of the platform, a bottom attaehed to the under side of the swinging frame serving to hold the lower run of the platform close to the rolls in the said swinging frame, worm wheels arranged on the shafts of some of the rolls of the stationary frame, projeetions on the said rolls adapted to engage recesses in the under side of the slats of the endless platform, anda worm shaft journaled at the side of the stationary frame and meshing with the said worm wheels, substantially as shown and described.

3. A eonveyer, comprising an endless traveling platform, two sets of rolls 011 which the platform is mounted, a stationary frame carrying one set of rolls, a swinging frame hinged on the stationary frame and earryin g the other set of rolls, a chute leading to the platform on the stationary frame, a tackle for raising and lowering the said swinging frame, a gate for opening and closing the lower end of the said frame, worm wheels arranged on the shafts of some of the rolls of the stationary frame, projections on the said rolls adapted to engage recesses in the under sides of the slats of the endless platform, and means for rotating the said worm wheels, substantially as shown and described.
